Specification of Letters Patent. I

Original application filed November 17, 1915, Serial No. 32,021. Dividedand this application filed July 5,

1916. Serial No. 107,658.

To all whom it may] concern Be it known thatI, FREDERICK E. HAND, ac1t1zenofthe Un1ted States, residing at Evansville, 1n the county ofVanderburg and State of Indiana, have invented certain new and usefulImprovements in Adjusting Mechanism for Plows; and I do hereby declarethe following to be a full, clear, and

exact description of the invention, such as will enable othersskilled inthe art to which it appertains to make and use the same.

This invention relates to adjusting mechanism for plows and has for anobject the provision of improved means for regulating the depth of thefurrow without interfering with the means for raising the plow from thefurrow. ii

With the foregoing and other objects in view, the invention consists incertain novel features of construction, combination and arrangement ofparts as will be more fully described in claims.

In the accompanying drawings, Figure 1 is a perspective view of the plowfrom the furrow side.

Fig. 2 is a perspective view on enlarged scale from the front showingthe operating mechanism in more detail.

Fig. 3 is a detail of certain structure shown at the left of Fig. 2.This application constitutes a division of my application filed November17, 1915,

' Serial No. 62,021.

I for attaching draft such as a tractor.

Before referring 'to the adjusting mechanism proper it may be statedthat the plow bottoms are indicated by 10 and these are carried uponbeams 11, any desired number being employed. The beams 11 are securedtogether adjustably by the braces 12 and are provided at their forwardends with ears 1;

connecting-structure composed of plates 14 and 15 is provided with aplurality of opencarrying a land wheel 23.

Rigidly secured to the frame composedof beams 11 and their braces is asegment 24 supported by braces 25. This segment is 22 is moved in itsbearings to raise and lowerl Patented Feb. 27, 1917.

' sTArEs PA'rE Ti )F I rnnnnnfo'x n. HAND, or EvANsvILLE, INDIANA,ASSIGNQR ro'rHn vULoA'N PLOW the lan-dwheel relative to the frame, orraise I and lower the frame relative to the land wheel. j

The furrow wheel 19 is also arranged to be raised and lowered relativeto the frame simultaneously with the raisingand lowering of'the landwheel, such connection being by means of arm 27 rigidly connected withaxle 18 and operating by a variable link connection with arm 28 rigidlymounted upon axle 22! This variable connection between the arms 27 and28 includes a bar 29 pivotally connected to the arm 28 and carrying asegment 30 rigidly secured to bar 29 by means of braces 31 and 32. A.lever 33 is pivoted to the brace 32 at 34'and is also pivoted to thearmi27 at 35. It is obvious that by manipulating lever 33, therelationof arms 27 and 28 to'each other will be changed, so that when arm 28 isactuated by the movement of arm 26, arm 27 will also be actuated, butits position relative to the arm 28 may be changed manually, as de-' sFor the purpose of assisting in raising the plows, springs 36 and 37 areemployed, the

spring 36 being pivotally connected to arm 27 at 38 and thespring 37being connected with arm 28 by link 29. These springs are .connected attheir front ends with draft plates 14 and 15.

The arm 40 secured to axle 22 is connected by. a chain 43 with'rod 42and thence withthe caster mechanism described in the co- 1 pendingapplication above referred to,-

wherein a power hoist 50 and means for controlling the latter aredescribed in detail and claimed.

An important feature of the present con struction is that the'arm 33.remains practically' stationary when the axles are shifted U by othermechanism, as for instance the power hoist referred to.

It will. lso'be observed that sinceaxle 22 and axle 18 are connected bymeans of the adjustable link construction, any adjustment of arm 26 willproduce a .corresponding movement of axle 18, and hence arm 26 willserve to secure all depth adjustments, while arm 33 serves only to levelthe plows crosswise by changin the relative position of the axles andthat o the wheels. i

What I claim is: 1. The combination with a plow frame, of a plurality ofbent axles mounted thereon,

' arms secured to the axles, a segment, segment supporting meansconnected with one said segment, and a'bar connected therewith.

3. The combination with a plow frame, of a plurality of bent axlesmounted thereon and arms extending from the axles, a substantially areshaped segment, a plurality of bracesconnected at the approximate centerfrom which the arc is struck and connected with the ends of the segment,a lever Copies of this patent may be obtained for and arms extendingfrom said axles,

pivoted to said means and fillengaging the segment and fulcrumed on onearm, and means for conneetingthe braces with theother arm.

' 4. The combination with a plow frame, of a plurality of bent axlesmounted therepn, o a segment, and means for directly supporting thesegment, a bar connecting the su porting means with one of the arms, anda ever engaging the segment and pivoted to the other arm and to thesupporting means at substantially the'center from which the arc of thesegment is struck.

5. In a plow, a frame, a set of crankshafts on said frame with parallelportions, each having crank arms, a lever pivoted on one arm, and asegment having pivotal connection with said lever and the other. arm.

6. In a plow, a frame, a setfof-parallel crank shafts on said frame,eachhaving anarm, a link structure pivotally' connected to one arm,v anda lever pivoted upon the other arm and .to said structure and operativerelative thereto to vary the. angle between said arms, and havinglocking engagement with said link structure. I 1

7. In a plow, a frame and a-palr of, parallel crank shafts thereon, eachhaving an arm, and linkage adjustably connecting said arms comprising amember pivotally connected to one arm and alocking lever ad- 'justablyconnected at one end to said member and pivoted intermediate. its lengthupon the other arm.

In testimony whereof I aflix my signature.
